Molded Grating Pedestals

For more than 30 years, Fibergrate customers have been taking advantage of the benefits offered by using Fibergrate’s grating pedestals to create elevated flooring. Now these pedestal offerings have been improved to offer more adjustability for added grating configurations. Fibergrate’s state-of-the-art grating pedestals are now offered for both Fibergrate® and Chemgrate® square mesh molded gratings in depths of 1”, 1-1/2” and 2”. This increased offering provides more flexibility in designing your raised flooring application as economically as possible.

Made with the same quality as all Fibergrate products, these specially designed pedestals are manufactured to provide safe support for elevated flooring. Pedestal supported floors are versatile; they can be modified or moved from place to place as necessary and pedestals are generally more cost effective than beam support systems. Pedestals take full advantage of the bidirectional strength of square mesh molded gratings, eliminating additional costs of structural shapes, drafting, fabrication and installation.

Adjustable pedestals are available in heights from 3-1/4” to 42” (up to 72” with additional bracing - contact Fibergrate for more information). Pedestals are available with single heads for 1-1/2” and 2” square mesh grating and quad

heads (for panel abutments and corners) to fit either Fibergrate® or Chemgrate® brand square mesh molded gratings. The ease of adjustability of the pedestals will save installation time on sloped floors. Single heads can be adjusted from atop the grating with a 1/2” drive socket, dramatically decreasing time spent during the leveling process, especially in floors under 18” high or where obstructions are present. Reference pages 7 - 11 for layouts and page 4 for pedestal configurations and part numbers needed.

These injection-molded, fire-retardant, glass-filled grating pedestals are low maintenance, as are all of Fibergrate’s products, providing excellent corrosion resistance. They are designed to be resistant to most industrial wet floor applications such as plating, clean rooms and wash down areas.

• Adjustable - Can be installed to create a level walking surface even on sloped floors. Adjustable pedestals are available in a selection of designs ranging in height from 3-1/4” to 42”. Single head legs, used in center of large panels, are designed to be adjusted from the walking surface - eliminating the need to access from underneath.

• Versatile-Uniquely designed system can be used with all depths of both Fibergrate and Chemgrate square mesh grating. • Easy Installation - Efficient design affords quick adjustment and simple installation layouts. Lightweight pedestals and grating can be installed without heavy lifting and fewer people. The system does not require floor penetrations.• Most Cost-effective System - Economical way of providing a raised flooring structural support system. Compared to standard braced support systems, Fibergrate’s pedestals maintain the lowest installed cost for elevated flooring. The elements can be easily repositioned as required for new layouts and designs.• Lightweight - Modular concept and lighter weight component materials promote faster installation with fewer laborers and no lifting equipment.• Corrosion Resistant - Made with thermoplastic polyester and pultruded vinyl ester parts, pedestals are designed to be resistant to most industrial wet floor applications for long service life. • Nonconductive-FRP pedestal support heads provide electrical insulation from the supporting surface making the system safer for workers.

1. Use the layouts given on pages 7 through 11 and select the required grating and pedestal layout based on the grating depth, the most efficient panel utilization, and the load and deflection requirements for your installation. Refer to the project specifications for loading and deflection requirements. If designing for pedestrian loads, use the layout for 50 psf (pounds per square foot)/300 lb point loads. If your requirements differ from the ones listed, contact Fibergrate for assistance.

2. Following this layout, sketch a plan view of the installation that shows the grating panels and the pedestals, indicating which pedestals have single heads and which have quad heads. Fibergrate® gratings require the Fibergrate® Quad head and Chemgrate® gratings require the Chemgrate® Quad head. The 1-1/2” Single Head works for 1-1/2” square mesh gratings of either brand and the 2” Single Head works for 2” square mesh gratings of either brand.

3. Determine the maximum and minimum ‘A’ dimension of the grating installation. The ‘A’ dimension is the distance from the bottom of the grating to the floor. There is not an adjustable pedestal for ‘A’ dimensions of

less than 3-1/4”. If your A dimension requirement is less than 3-1/4”, alternate solutions such as fixed height legs or rubber feet may be possible. Contact Fibergrate for assistance in developing a support system for your application.

4. Once you have completed your layout and know the lengths of your pedestals and which heads you require, use the chart below to select part numbers for your order. It may be necessary to use several different pedestal heights for a given installation. For example, if the ‘A’ dimension of your installation ranges from 14 to 20 inches, two heights of pedestals are required. Note that all of the adjustment ranges overlap by from 1” to 3” so that there is some flexibility built in for errors in height measurements or pedestal counts.

Installation TipsDue to its versatility, there is a wide variety of applications for Fibergrate’s grating pedestal system; therefore, installation will vary depending on the specific application. Thought and planning are the key ingredients to a smooth and trouble-free installation. Step1 Surveyareatobecoveredwithpedestalsupport

system. Plan a starting and ending point. (Typically, areas are started in the corner containing the longest straight edge of the surface to be covered.)

Step2 Assemblethelegcomponentsreceivedaccordingto height required to provide a level supportsystem and place adjacent to the first row of grating to be installed.

Step3 Install pedestals according to the layouts andload specifications provided on pages 7 - 11 of this brochure.

Step 4 Adjust grating pedestals of first row of grating panelstocreatealevelwalkingsurface by rotating the bases or the quad heads under the grating by hand

and the single heads with a 1/2” drive socket from walking surface. Take care not to adjust beyond the red maximum adjustment mark on the stainless steel adjustment rod.

Step5 Layoutsecondgratingpanelrowtobeinstalled.Connect second row to first using the exposed portion of the quad heads. Continue installing row two according to Steps3-4.

Step6 Repeat steps3 -5until installation is complete.Trimming of panels on last row is normally required for close fit.

InstallationNotes:1. Most contractors find the use of a laser level significantly

speeds the leveling process during installation.2. Fibergrate grating pedestal system is designed to provide

structural support for walking surface; however, lateral support should be provided through attachment to adjacent equipment or containing the grating within perimeter walls of grating layout area.
